6.14 Electromagnetic Induction/ Aruhan electromagnet

Diagram 4.1 and Diagram 4.2 show a cross sectional of bicycle dynamo which has a magnet
and a coil of insulated copper wire. The output of dynamo is connected to a bicycle lamp.
When the magnet is rotated by turning the wheel with same speed, the lamp in Diagram 4.2 is
light up brighter than in Diagram 4.1.
Diagram 4.1 dan Diagram 4.2 menunjukkan keratan rentas dinamo basikal yang mempunyai
magnet dan gegelung dawai tembaga bertebat. Output dynamo disambungkan ke lampu
basikal. Apabila magnet diputar dengan memutar roda dengan kelajuan yang sama, lampu
dalam Rajah 4.2 menyala lebih terang daripada pada Rajah 4.1.
